Implementations

impl<'a, T, E> TaggedParser<'a, Explicit, T, E>

pub const fn new_explicit(class: Class, tag: u32, inner: T) -> Self

pub fn from_ber_and_then<F>( class: Class, tag: u32, bytes: &'a [u8], op: F, ) -> ParseResult<'a, T, E>

where F: FnOnce(&'a [u8]) -> ParseResult<'_, T, E>, E: From<Error>,

Parse a BER tagged value and apply the provided parsing function to content

After parsing, the sequence object and header are discarded.

Note: this function is provided for Explicit, but there is not difference between explicit or implicit tags. The op function is responsible of handling the content.

pub fn from_der_and_then<F>( class: Class, tag: u32, bytes: &'a [u8], op: F, ) -> ParseResult<'a, T, E>

where F: FnOnce(&'a [u8]) -> ParseResult<'_, T, E>, E: From<Error>,

Parse a DER tagged value and apply the provided parsing function to content

After parsing, the sequence object and header are discarded.

Note: this function is provided for Explicit, but there is not difference between explicit or implicit tags. The op function is responsible of handling the content.

impl<'a, TagKind: PartialEq, T: PartialEq, E: PartialEq> PartialEq for TaggedParser<'a, TagKind, T, E>

fn eq(&self, other: &TaggedParser<'a, TagKind, T, E>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T> ToDer for TaggedParser<'a, Explicit, T>
